Okay, here are several steps that should help improve performance:
1. Firstly, make sure you have run anti-virus and anti-spyware tests on your computer, as this could be a source of lower performance. If you don't have any programs, or aren't sure about the ones you have, you should download:
AVG 8 - A good free anti-virus

Ad-Aware - Anti-spyware

Malwarebytes - Another good malware scanner & remover

2. Now, there are several windows tools that can be used to speed up your comp:
- Go to start, click run, and then type in msconfig. Click on the start-up tab, and this gives you a list of all the programs that start when you turn on your computer. Turn off (untick) anything that isn't your anti-virus, anti-spyware, and any other programs you want to start up e.g. maybe MSN Messenger.
- Go to start, click my computer, right click on Local (C) drive, click properties, go to tools. Then click on error checking, and click check now. This helps fix problems on your hard drive. NB: This can take a while
3. Next up, there are several very programs that I would advise you download:
Glary Utilites - This has a wide range of tools which are used to speed up your computer, registry defrag, cleaner, temp file remover etc, all of which help with performance.

Smart Defrag 1.1 - This helps defragment all of your programs - this makes them open quicker and respond better.

CCleaner - This helps remove other files like internet history and cleans your registry to speed up your comp.

(All programs here are safe and virus/ad-ware free)
4. I advise downloading the latest Mozilla Firefox, along with an add-on called Fasterfox, to increase your internet browsing speed. This is an excellent and quick way to surf the web.

5. Fianlly, I would also advise you remove any programs you no longer use, as they can take up a suprising amount of space. Go to control panel, and click add/remove programs. Don't remove anything you need though.
These stages should be effective though in speeding up your computer.
Hope this helped
Good luck
